2 Claims.

The invention relates broadly to improvements in waxed wrapping papers and, the wrapping of articles therein.

It is common practice to utilizewaxed paper 6 in the wrapping of bread and other articles, the

wax on the folded ends of the paper being softened or melted to cause the folded ends to stick together and hold the paper in wrapped position. A comparatively thin coating of wax is ordinarily employed and difficulty is encountered in securing a sufficient adhesion of the folded parts to thoroughly protect the wrapped articles, and to provide a package that will not open in handling.

An object of the present invention is to provide means in connection with the waxed surface to bring about a thoroughly effective adhesion in the wrapping operation, and a complete protection of the enclosed article against loss or gain seal in ordinary handling.

In order to attain this object there is provided in accordance with one feature of the invention, a coating of latex rubber, or of rubber dissolved in solvent, which coating is applied either to the entire sheet or to the sealing areas of the sheet. This coating is preferably applied underneath the wax. Then, when the paper is folded and the wax softened, the coating underneath the wax also becomes softened and embodied with the wax'to bring about a firm adhesion.

These and other features of the invention will be more specifically set forth in the following description and the accompanying drawing, 35 wherein:

Figure l is a plan view of a sheet of waxed wrapping paper shown partly broken away and embodying the present invention utilized in connection with the sealing area of the paper.

Figure 2 is a sectional view through the sheet illustrated in Figure 1.

Figure 3 is a view of a sheet of wrapping paper, shown partly broken away, embodying the present invention applied to the entire sheet; and

Figure 4 is a sectional view of the sheet illustrated in Figure 3.

In carrying out the present invention the adhesive coating, as the latex rubber, may be applied to the sealing area, as illustrated in Figures 1 and 2, or may be applied to the entire sheet, as illustrated in Figures 3 and 4.

Referring to the drawing in detail, I indicates the base sheet. To this base sheet is applied a coating of the adhesive material, such as the latex rubber 2. In Figure 1 the adhesive material 2 is shown applied to the sealing areas of of moisture, and against failure of the wrapping the base sheet. This may be, as shown in Figure 2, either as one coating covering the sealing area, or applied in strips across the sealing area; 'or, as shown in Figure 3, may be applied over one entire face of the base sheet. The base sheet is then covered with the ordinary wax coating 3, as shown in the drawing.

It isonly necessary to apply the extra adhesive coating to one side of the base sheet, the wax coating on that particular side of the base sheet covering and protecting this extra adhesivecoating, as shown in Figures 2 and 4. The extra adhesive coating may, if desired, however, be applied to both sides of the base sheet.

In utilizing wrapping paper constructed in accordance with the present invention, the surface of the sealing area of the paper, after the article is wrapped, is in the usual manner softened or melted. This operation softens the adhesive coating as well as the covering wax, causing the extra adhesive coating to become mixed with the wax, bringing about a particularly firm and complete adhesion of the sealing surfaces. The wax covering for the extra adhesive material 2 protects the same, keeping the sheets from sticking together until the softening process.

It has been found by use that with the present invention all previous objections to the use of wax paper for wrapping purposes, due to its lack of adhesiveness, is obviated and that a thoroughly ,bomplete adhesion of the sealing areas is secured, bringing about a complete sealing protection of the wrapped articles. i

I claim:

1. A wrapping paper of the class described, including a base sheet, a coating of latex rubber covering the sealing areas of said sheet, a second coating comprising a layer of wax covering the entire base sheet including the adhesive layer, said adhesive layer and. wax coating being separate layers adapted to commingle only when correspondingly treated portions of the paper are brought together and the wax softened.

2. The method of treating the adhesive quality of a sheet of paper, consisting of applying to the sealing areas of one surface of said sheet a coating of latex rubber, and then so covering said entire sheet and said coating with a separate layer of wax that the layer of wax will not be admixed with the adhesive coating, but will upon softening commingle with the adhesive coating to increase the adhesiveness of the waxed surface when correspondingly treated portions of the paper are brought together and heat applied thereto.
